For the second time this month glass panels on the balconies of the Austin W Hotel have broken and, as a result, the hotel will be replacing every balcony glass panel-nearly 1,000. This incident follows a similar one on June 10 when three people suffered minor injuries. No one was hurt yesterday, though five parked cars were damaged. A statement issued by the W Austin Hotel notes that “engineering and glass experts are investigating and we continue to cooperate with city officials …” At this time the reasons for the glass breakage have yet to be determined. Some in the glass industry say there are many possible causes of such incidents.
